Description
Technical field
The present invention relates to a kind of friction material, in particular it relates to a kind of resin base for brake block for brake block
Friction material.
Background technology
Within 1897, invent first piece of brake block in the world, and for carriage and automobile in early days, sent out in 1909 subsequently
Bright first solidification asbestos base brake block, nineteen sixty-eight invention first semimetal base brake block in the world, hereafter, friction material is opened
Begin to develop to without asbestosization.Begin one's study both at home and abroad the alternative fiber such as steel fibre, glass fibre of various asbestos, aramid fiber,
The application on friction material such as carbon fiber.Although the kind of reinforcing fiber is a lot, a kind of fiber is not had to become completely
Replacing asbestos in this and performance, therefore research the most in recent years has gradually turned to assorted fibre from Single Fiber.
The Main Function of adhesive is each component of brake block to be closely bonded together, and keeps brake block at high-temperature machinery
Structural intergrity under Zuo Yong.Adhesive most-often used in brake block is phenolic resin, it have excellence heat resistance and
Mechanical performance, electrical insulating property and moulding processability are good, and raw material is easy to get, low price, and technique and the equipment of production are simple.But
The use of pure phenolic resin can cause brake block much higher hard, fragility big, and heat-resistant limit temperature is only about 250 DEG C.When exceeding
When 300 DEG C, thermal decomposition phenomenon is quite serious, and the performance of brake block can be caused to be remarkably decreased.Therefore phenolic resin must be carried out
Toughness reinforcing and heat resistance modified.
The modified resin abroad used mainly has Effect of Organosilicon-modified Phenol-formaldehyde Resin, boric acid modified phenolic resin, hydrocyanic ester modified
Phenolic resin, epoxy modified phenolic resin etc..Wherein utilize boric acid modified phenolic resin prepare the brake block that 400 DEG C time
Wait, remain in that higher coefficient of friction, but this friction material is relatively costly.
Existing friction material generally includes a few portion of binding agent, reinforcing material, frictional property regulator, filler and compound
Point, wherein binding agent typically uses phenolic resin to do raw material, and it has the drawback that: poor heat resistance, and heat decomposition temperature is low, uncomfortable
Close the production of high temperature friction sheet；The cohesive strength of resin is low, and the wear rate causing friction goods is high, and service life is short；Resin
Poor toughness, vehicle can produce noise when brake, the frangible damage of friction plate；Free phenol content is high, and the friction plate produced is fine and close
Property is poor.Such friction material can not meet market demands.The research of China's brake block is more late than abroad starting to walk, and sends out with the world
Reach country and also have bigger gap.
Summary of the invention
The present invention solves the problems referred to above, it is provided that one has good hardness, thermostability, heat stability, resistance to water, glues
The resin-matrix friction material for brake block of knot property.
The present invention is made up of the component of following number for the resin-matrix friction material of brake block, and described number is weight

Wherein said phenolic resin synthesizes by the following method:
At room temperature, add 0.8-1kg phenol, 2-3L dioxane, 0.5-0.8kg paraformaldehyde to reactor successively,
It is warming up to 80-100 DEG C after stirring 1-2h, after reaction 4-5h, pours vacuum distillation apparatus into, excess of solvent is distilled off through decompression,
After pouring out hardening by cooling, stand-by with flour mill pulverizing.
Described Tin disulfide, calcium carbonate, for commercially available 200-300 mesh product.
Described aluminium oxide, white carbon are commercially available 250-350 mesh product.
Described polyacrylonitrile fibre, aramid fiber are 20-30cm chopped fiber.
The present invention is as follows for the resin-matrix friction material preparation technology of brake block:
Phenolic resin and other components are sequentially added into JJ-5 type glue sand machine mix homogeneously, by hot press 190-230 DEG C
Lower hot pressing 8-12h molding, obtains the present invention resin-matrix friction material for brake block.
The present invention is had the beneficial effect that
1, the present invention is heat-resist for phenolic resin used by the resin-matrix friction material of brake block, and hardness is high, rub resistance
Excellent performance；
2, each component synergism so that the present invention not only hardness is high, and toughness is preferable；
3, synthesis route is simple to operation.
